Abstract: A pre-determined amount of solubilized reagent is reacted to release CO₂ in a controlled-temperature reaction vessel and a controlled-pressure area adjacent the reaction vessel. 
     The devices that enable the system to be maintained in the liquid phase, and the reaction vessel itself, are controlled, assuming that the O₂ in the solution is such as that deriving from the presence of O₂ in the atmosphere, if necessary corrected for the effect of the reaction producing CO₂. 
     Thus, the amount of reagent taking part in the reaction being known, either by assay or by controlling the reaction time, by controlling the amount of O₂ in the solution containing the reagent, the barometric pressure, the temperature in the reaction vessel, and the coefficients of solubility of the two gases, it becomes possible to predict the partial pressures of O₂ and CO₂ in the liquid phase produced, which liquid phase is suitable for use as a calibration substance for an apparatus for measuring blood gases.

Abstract: A method and system for color and monochromatic printing wherein ordered dither and error diffusion processes are combined to provide high quality printed images with good spatial resolution, good gray scale transitions, good low frequency and high frequency responses and a high computational speed. Using this process, gray scale numbers representative a of scanned (10, 36) image are summed (56, 58, 60, 62) for each super pixel of the scanned image and divided (72, 74, 76, 78) by a chosen gray level normalizing factor. This division operation is done to obtain a normalized ordered dither quotient number of drops (dots) (C Q , M Q , Y Q , K Q ) to be printed in super pixels and to further obtain an error remainder number of dots (C R , M R , Y R , K R ) to be dispersed to surrounding super pixels. The normalized ordered dither quotient number of dots are printed (146) in pre-assigned individual pixels within printed super pixels, and the error remainder number of drops are diffused (112, 114, 116, 118) to other pre-assigned surrounding or adjacent super pixels. In this manner, a combination of ordered dither and error diffusion signal processing and printing is achieved to simultaneously take advantage of some of the best characteristics of both types of signal processing printing. 
     In color printing, the above operation is carried out in each of a plurality of separate color planes (C, M, Y, K), and all of the quotient information (C Q , M Q , Y Q , K Q ) is retained and printed (146) in a predetermined priority sequence for each color plane. Thus, this invention is not only operative to retain the maximum amount of image data for each color plane (C, Y, M, K), but it is printed in an output matrix of super pixels in such a manner as to maximize overall print quality of the reproduced color image.

Abstract: An improvement in web-converting rewinders of the type which includes a perforator cylinder, and a bedroll/chop-off roll combination (21, 23) comprising a set of chop-off blades (31, 32), some of which chop-off blades (31) are disposed on the bed roll (21), and some of which (32) are disposed on the chop-off roll (23); and in which a running web is forwarded from an unwinding parent roll, and is converted into consumer product rolls such as, for example, tear-separable multi-sheet rolls of toilet tissue or paper towels. The improvement comprises parallel-motion chop-off blades (31, 32) which can be more closely spaced than in prior art chop-off blades, and thus induce greater stretching and more positive breaking of the web; and, preferably, the chop-off blades (31, 32) are disposed to act on a longer machine-direction-length of the running web than contemporary rewinders to enable more positively inducing roll endings by breaking along transverse lines of weakening rather than by inducing ragged transverse tears of web. Such a disposition of the chop-off blades (31, 32) is said to provide a wider window in which the lines of weakening in the running web may be indexed during each roll-ending chop-off event. Such an indexed relationship between the chop-off mechanism (20) and the running web is easier to continuously maintain with such a wider window, all other factors being constant. This invention is particularly useful for webs such as creped paper which must be stretched substantially in the machine direction before they will break along transverse lines of weakening such as lines of spaced cuts or lines of perforations.

Abstract: A bilevel current limiting control circuit which enables a semiconductor controlled power switch with a limited power handling capability to operate near the inside border of the safe operating area (SOA) characteristic of the power switch. The control circuit is especially useful in limiting the turn-on inrush surge current to an incandescent lamp load supplied via the semiconductor power switch. The control circuit includes a series circuit made up of the power switch, a current sensing resistor and a lamp load connected to the terminals of a source of supply voltage. First and second comparison circuits, arranged to provide first and second different current limits for the control circuit, are connected to the sensing resistor. A third comparison circuit compares the load voltage with a reference voltage to control a selector device that selects the output of the first or second comparison circuit as a function of the level of the load voltage. The output of the selected comparison circuit is applied via a feedback circuit to a control electrode of the power switch so as to control the load current to the first and second current limit values as selected in response to the load voltage.
